Please help me answer these 10 questions. These are all Java related.

I really appreciate it.

Self-Assessment Exercise: Round-Off Error Objectives See the effects of the IEEE 754 standard on floating-point calculations and round-off errors Instructions For this quiz, you need to create some simple code that performs some multiplication operations and prints out the results. You do not have to submit your code Float calculations Initially, declare a float variable and give it the initial value 3.0 float number 3.0f: Now, multiply the number by 10 and print out the value, using default precision as shown. number10.0 System.out.println (number) Repeat this 20 times. (Yes, this would be a natural place to use a loop. You wil find it helpful if you print out both the new value of number and the iteration. So, iteration 1 prints out 30.0; iteration 2 prints out 300.0, etc.) The expected final value is 3 1020 However, the computed value is 2.9999997E20. This value is well below the upper bound for float values, which is around 3.4 1038 The numerical output is not the mathematically expected result due to the round-off error inherent in floating-point numbers (float and double) as described in IEEE 754. In this case, obviously, the round-off error is in the float data type Use this simple program to answer the first four questions in the quiz. 1. What is the value where the round-off error is first apparent? 2. Which iteration is the round-off error first apparent? 3. What is the significance of the letter 'f in the assignment of the initial value of the variable number? 4. What happens if the f is omitted in the initial value
